After I figured out how I can use Python to create Pig UDF functions, I got interested in Jython and wanted to play around with it. So I installed it in my Mac through homebrew by executing the following command.

brew install jython

Everything got installed properly, I was able to run Jython after setting
up the following lines in my [bashrc](https://github.com/sudar/dotfiles)

But there was one small annoyance. Every time I was staring Jython, I was getting the following strange warning.

expr: syntax error

After a couple of web searches, I stumbled upon an email thread in the Jython-users mailing list. Basically it was due to a bug in the bash script that is used to start Jython. I opened /usr/local/Cellar/jython/2.5.3/libexec/bin/jython file and changed the line, which fixed the error.
